"@Martin GW
I made a pretty good setup description for this youtube video, just type it here:

My own KroozX combo flightcontroller with OSD and proper Blheli_S ESCs https://www.flickr.com/photos/1503764...

Sergey commented on Laser Developer's blog post DIY LiDAR scanner using the LW20 and a digital servo
"Very nice device!
Btw, what would be a stable measurment range of LW20 on full 388 readings/s speed? Or other way - will LW20 be able to measure up to 100m with good reflecting surfaces on the full output rate speed of 388Hz?"

Sergey commented on Nadia Nilsen's blog post LightWare launches the LW20 LiDAR
"Should be the most powerful and small consumer lidar ever. Can't wait to test it!
Is there going to be an OEM version (without enclosure) available?"

Sergey commented on Gautier Hattenberger's blog post Multi-UAV flights for simultaneous meteorological measurements
"@Marc Dornan,
as Gautier already said, the KroozSD board has an onboard MAX7456 osd which works with the corresponding software module under Paparazzi. It has rather basic functionality, but, as you said, the Paparazzi project is pretty easy to get…"

Sergey commented on Pete Hollands's blog post Drones are not ready for the mass consumer market
"Here is an example, how a drone with a lot of sensors does the same exercise:

In most cases the problem is definitely not in the drone."

Sergey commented on Daniel McKinnon's blog post Navigating the byzantine FAA Part 107 exam registration process
"What gimbal is on the picture? Looks like a brushless one. Is it already available?"

Sergey replied to Charles Linquist's discussion Intentionally shutting off motors in mid-flight then recovery
"Turning the motors during flight is dangerous, it's really possible, that they won't spin up again.
Isn't it a better way to somehow increase the descend speed?"

"Btw, there is currently an Atom based dev board already available:
MinnowBoard Turbot"

Sergey commented on Emlid's blog post Reach RTK Pixhawk integration released!
"Good progress!
Btw, is it a GPS antenna on the top of the rod? What is the actual reason for such antenna placement?"

Sergey replied to Neil's discussion LiDAR on Stabilised mount
"Check out this DIY project:
DIY 360 degree realtime outdoor LIDAR
Looks like they use it on up to 10Hz rotation scan rate.
However Lidar Lite sensor availability is still a big question."

Sergey replied to Nick's discussion Iris+ shaking GoPro Hero4 in IRIS
"If your gimbal mounted on rubber dampers, tightening them or using a stiffer ones could help here."

Sergey commented on Thomas J Coyle III's blog post Hybrid Power Could Help Drone Delivery Take Off
"Doesn't seem they have a working device yet. Looks like they want to investigate the demand in such devices first or pick a big investor. Well... business."

Sergey commented on Jiro Hattori's blog post Two hour and 12 minutes flight by PEM fuel cell
"@Gerard, thanks for your comment!
Actually I did a short ~1min take off before my record flight, but 2h10min are still less than 2h12min.

Anyway, the guys done a great job.
But, when it comes to fuel... I think there is much more potential in a…"

Sergey commented on Emlid's blog post Navio+ and Odroid-C1: the most powerful Linux autopilot
As I understand, having deal with linux kernel and driver mods to connect all peripheral and devices needed to fly is much more time consuming and error prone, rather than have a simle singe communication bus to transfer flight/sensor data…"
